PUMP.

SPECIFICATION forming part of Letters Patent No. 787,308, dated April11, 1905.

Application filed December 8, 1904. Serial No. 235,986.

be it known that I, \VtLLL-m M. Pinon, a citizen of the United States,residing at Oshkosh. in the county of 'innebago and State of \Yimzonsin,have invented new and useful Improvements in Pumps, of which thefollowing is a specilieation.

i\Iy invention relates to pumps ot' the class used in wells.

The essential features of my invention are the construction of thesupporting-arm and hearing-howl in two parts; the construction of thesupporting-arm and bearing-heml in two parts and bolting the partstogether; the construction of the supporting-arm and bearing-head in twoparts, the same being provided with an interior annular recess adaptedto inclose a corresponding projection upon the pump-head: theconstruction of the supporting-arm and bearing-head in two partsprovided with an interior annular recess adapted to inclose acorresponding projection upon the pump-head, and means for binding thetwo parts together around the pump-head.

.\ly invention consists in certain other new and novel features, whichwill be hereinafter set forth.

In the accompanying drawings, Figure l is a side view of a pumpembodying my invention. Fig. '2 is a vertical section of thebearing-head upon the line A A of Fig. 1. Fig. 3 is a front view, Fig. atop view, and Fig. an interior view, of one part of the support ing-armand bearing-hezul.

Similar numerals refer to similar parts throughout the several views.

2 represents the pump-head provided with an annular projection 3 and ashoulder i.

5 represents the bearing-hezul having an annular recess 6 correspondingwith the projection 2 and adapted to rest upon the shoulder Hi. Thebearing-howl and supporting-arm T are integral with each other and arecast in halves, as shown in Fig. 5, and brought together and secured bynuts and bolts 8 8, passing through the eyes 9 9. This forms a cheap Thenuts upon the bolts 8 8 may be tightened, so as to form an effectivebearing entirely around any pump-head.

In pumps heretofore used it has been usual to secure the l )earing-headto the wimp-head by means of a set-screw. My invention provides asimpler and more secure means of attaclunent.

The pump-rod l0 slides in the aperture ll of the supporting-arm T andalso in a rod-receiving aperture formed in the part 5, which includesthe pump-head. The casting of the simporting-arnl T in two partsobviates the necessity of providing a core for the aperture 1 1. Thissimplilies and cheapens the construc tion.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a pmnp ot' the character described, a rod-bearing including a headcomprising oppositely-disposcd similar contacting sections forming acentrally-disposed rod-receiving aperture thercbctween, means forsecuring the sections together, and a supporting-arm formed of similarsections one section being integral with each head-section, saidarm-sections forming a rod-receiving aperture therebetween.

2. The combination with a pump-head having an annular projection thereonand an annular shoulder parallel with said projection; of a bearing-headsurrounding one end of the pump-head and extending over said end, saidbearing-head consisting of oppositely-disposed similar sections bcaringon the shoulder and having an interior annular recess engaged by theannular projection on the pump-head.

3. The combination with a pump-head having an annular projection and ashoulder; of a bearing-head mounted upon the shoulder and surrounding aportion of the pump-head, said bearing-hezul consisting ofoppositelydisposed similar sections engaging the annular projection onthe pump-head and extending from one end of said pump-head, saidsections having registering recesses forming a centrally -disposed rodreceiving aperture, and means for binding the bearing-head sections uponthe pump-head and its projection.

4. The combination with a pumphead havbearing-head and said arms havingregistering recesses forming a rod-receiving aperture, and means forbinding the sections of the bearing-head upon the pump-head and itsprojection.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
